Be it known that I, Anocrun Oneness, e citicenlof the Republic ofFrance, and a 1:esi-

eve invented certain new and useful Improvefbr Explosion-Ention.

This invention relates to a device for producing ignition and v ders. Bythe use of this device the circuit of any one of the igniters me. bemaintained while'thecircuits of the ct era are broken, each cylinderobserved alone.

, The invention isillustreted in the accome 1 shows the device incrosssection;

Fig. 2 shows the, same partly in lo section and partly in elevation. 3is a cross-section through -a. modified cm of the device. Fig.4 is ediagrammatic view showing the connections between the controlling devicere resented'ct A, the body M of the driving-0y 'nders, theinduction-coils, and the accessory parts. Figs. 5 and 6 are a' section.and plan, respectively, of another embodiment of the invention.

For verifying or determining which, if any, is running without explo'sions an is thus a dead load on the engine a number of circuit-breakersare used, one beoonnectedto the ignition-circuit of each s the circuitof all but t e first cylinder the engine will stop or will continue inmotion, according as this c lor proper y.

.itudinel Similarly each of the other cy tested in turn.

Means are provided also for ccmplelinglihe circuit of sec lot theigniters by a path w 'ch passes around the usual interrupter and is thepositionef the latter or of the of the engine. Thus if. by the testingmechanism it be found that any one of the cylinders is running idly orwithout ignition a suitable buttonmey be pressed to cause ignitioninsaid cylinder by 7 way of a. shunt-circuit around the usual cirisstopped, b

4 mder which is in conspression ignition may be effected insaidcylinder.

t erunnm of 'theengineb explosion-engmes'hcving two or more cy y thecircuit would be through wire 7) inders rnsy be 7 fthe contact 1 of tthe proper moment as determined by the inran ed four testers orconnecting members in t e nature of brid es and eds. ted for breakingthe circuits 0% end as hereinafter explained, to seperetely verify therunning of each of the c inders of the motor by bearing upon the knobsC, which are arranged at the u per portion outside the casing. Each of tese rods or testers B is insulated from the mass of a lower socket orsleeve of ebonite a and also by means of its knob C, which is ofinsulating material. This rod B is in contact, by means of the pins 0,Fig. 2, with two strips?) l) which form two terminals in the primarycircuit of en igniter. The stri' s of one series communicate, throu 11wires with the automatic interrupter ,and the strips t of the otherseries are respectively connected, through wires b, (see Fig. 4,) to theterminals 1 l I P of the induction coils X X X K, respectively. Y

When one of the knobs C of the controller is depressed, the circuit isbroken, because the pin cleaves the strips 1) b. The igniter of thecorres ending driving-cylinder is thus cut out o circuit. Now if anythree knobs be do ressed simultaneously the igniter of the cy indercorresponding to the fourth knob will be the only one on a completecircuit, and if the operation of the engine is defective under theseconditions it must be that the operation of this cylinder is defective.For example, supposing the knobs C, C, and C to be depressed then, asindiceted in Fig. 4, 7 from the battery to P, thence through the riinelgcircuit of X, (the other circuits eing roken,) thence button C and biwire h and tenninal b to e interrupter K thence (at dicetor andcircuit-closer 'i on the shaft of the engine) to the central shaft andthrough wire I) to the engine M and beck to the battery. At the samemoment the the seconds? circuit of the coil X causes an o eretion o 7the correstpondin igniter us each cylinder may e teste or its operatingverified and the cylinder of which the operation is defective may bereadily ascertained. V

For starting the motor four other phase, Fig. l,provi ducting material,are errangedu of the casing andin electrics on the front the severeigniters and terminal 3 to the first induced current 111 ed with knobsD, oi non-con connection, (through the springs m, Fig. 1) with the en-.

gine M, as indicated by the Wire m, Fi 4. his circuit is by way of thebody M, Iiattery, connecting-point P and correspondin primary coil, wireI), stri b to rod B throug pin c. Thus if when t e motor is stopped oneof these knobs D is depressed the circuit is closed by the end of thecontact-pin d, carried by D, touching the rod B, and a spark is causedto ass in the corresponding ignition device is 1?, k or it whenever theshaft is in the proper angular position, as indicated by the interrupterK. The secondary circuitls from the igniter through the secondarywinding of one of the coils X X X X and back to the body of the engine.

The interrupter K comprises a fixed disk and a central shaft driven bythe engineshaft and making connection through the circuit-closer &successively with the four contacts on the disk. As there is never morethan one cylinder which is in the phase of compression of the gaseousmixture and as it is necessary to know which this cylinder is in orderto produce the spark there, the part i. is used as a combined contactmember and indicator, bein mounted upon the shaft and forming part 0%the interrupter K and showing the number 1, 2, 3, or 4 of the knob Dwhich should be depressed. The knobs C may also be used for startin Inthis case (see Fig. 3) the stri s b are cut away from the rod at themidd e point of their length' that is to say, at o. T e rod normallystands in its highestposition with the pin in contact with the ends ofthe strips b b. When lowered to the middle position illustrated, thecontact is broken. When the rod B is deressed to its fullest extent, itmakes contact its biid o the en ine by its owest part at m.

T e device ascribed above for controlling the ignition of the cylindersrenders it possible to operate with only one two, or three cylinders, ifdesired. It is only necessary to press upon a suitable number 0 knobs Cso as to interrupt the electrlcal communication for the correspondingcylinders.

The device shownin Figs. 5 and 6 consists of a disk of insulatingmaterial E, in which areformed concentric grooves for the reception ofcircular conducting-strips (1, connected-in pairs to the conductorsforming the circuits of the four cylinders. They are eight in number andare hereinafter designated by their numbers. These strips or blades arearranged in such a manner as to be capable of connection in pairs 1 2, 34, &c., by means of a transverse bar 9 h, of insulating material,carrying metallic contacts or rubbers I I I Z, coming into contact withthe conductingstrips d upon the disk. This bar is in two arts 9 and hand :otates around its axis I The one part g, by means of a spring ,isgiven a flat bearing upon the circular con uctors d, numbered 1, 2, 3,4, 5, 6,7, and 8.

pin 0 with the stri s b and with the The metallic rubbers l l l lestablish communication between the conductors as follows: Z between 1and 2, 1 between 3 and 4,

1 between 5 and 6, and l between 7 and 8. In this manner the fourcircuits are closed individually and can only be opened by an anularmovement of the cross-piece garound its axis 1. The other side it isalso movable around the same axis I; but it is articulated or movable atO and maintained in its raised position by means of a sprin r.

The circular conductors d orm together a continuous contact during aboutone-third of a rotation of the bar 9. By continuing this movement stillfurther the current is only closed from 1 to 2 when the bar lies Withinthe angle y. The three other circuits are open. One cylinder only istherefore operat- In three successive angular positions are arrangedcontacts 6, connecting the con ductors 3 to 4, 5 to 6, 7 to 8. When thebar 9 is turned to overlie any one of these airs of contacts, thecorresponding rubber establishes communication and ignites thecorresponding cylinder. These contacts, as shown,

. are connected below the face of the disk with the conductors d. Itwill therefore be a parent that in order to verify successive v theoperating of the igniters of the four cylinders it is only necessary tobring the movable bar 9 upon the corresponding contacts by turnin iteither by means of a knob or handle, w ereupon thecylinder which doesnot ignite is indicated.

In order to produce ignition, the pivoted portion h of the bar may beemployed. For this ur ose the conductors d are rolonged circu ar ybeneath the face of the isk E and are connected each to two contacts f,said contacts being in successive pairs around the plate and being allin ositions such that when the said part h of t e bar is above anyv pairof these contacts the other part 9 invariably closes the fourcircuits; Acircular conductor '0, connected to the bod of the en inc, surrounds theportion of t e plate which carries the contacts 1' serving for theignition.

When the pivoted part h of the bar is depressed upon any two of thecontacts its metallic portion connects that one o the conductors d, Fi6, which comes from the primary coil the body of the engine, and thuscom letes the primary circuit. (See Fig. 4.) he spark passes in thecorrespondlng cylinder and the motor after being started continues torotate, since the part fr diametrically opposite always closes the ourcircuits. Any izylinder may be ignited in this manner. e bar may also bemoved to a osition in which none of the circuits is comp etc, but allare interrupted.

Having now particularly described and ascertained the nature of mysaidinvention and in what manner the same is to be performed, I declarethat what I claim is- 1. In a multiple-cylinder explosion-em gine, thecombination of igniter-circnits tor the several cylinders, testers insaid circuits, and springs tending to hold said testers in position tomaintain said circuits com lets, said testers being independently operais to break their several circuits and thereby permitting ofdetermining, by operatin all but one of the testers, which, if any, cyinder is defective.

2. In a multipie-eylinder explosion-engine, the combination ofignitcr-eircuits for the several cylinders, terminals 3: b in saidcircuits, testers B independently operable, one for each air ofterminals, adapted in one position to ridge said terminals and completethe circuit, and in the opposite position to open the circuit, andsprings tending to hold said testers in positionto complete thecircuits, said testers erlnitting of deter-mi in by moving all ut one,which, if any, cy inder of the engine is defective.

3. In a multiple'cylinder explosion-engine, the combination ofigniter-circuits for the several cylinders, testers in said circuits, srings tending to hold said testers in position to maintam said circuitscomplete, said testers independently erable to break their severalcircuits and t ereby ermitting of determining, by operati all ut one ofthe testers, which, if any, c fiinder is defective, and ahand-controlled evice for completing the prime circuit of any one of theigniters at will w ion the engine is not running, 7

4. A device for verifying or controlling ignition of the cylinders ofexplosion-engines, comgrisin in c0mlnnation, a plurality of in openently-operable testers one for each cylinder and each provided with aconnecting member normally connecting two terminals in the primarycircuit of one of the igniters, said members ermitt' of determining, bmoving all lint one 0 said members, whic if any, 0 linder of the engineis defective, and means whereby the farther movement of said mem berscompletes the primary circuits and produces ignition.

In witness whereof I have hereunto si ed my name in the presence of twosubseri ing witnesses.
